It demonstrates the principle of an eddy current brake and conversely the effectiveness of laminated transformer cores for reduction of eddy currents. In other words, we can look for defects in a variety of metallic materials using eddy currents and never harm the material that we are testing. Mar 25, 2010 - 1 min - Uploaded by sbjornfThis is an example of an eddy current generated by a Neodymium magnet on a piece of copper. We have learned that all matter is composed of atoms and that atoms are composed of protons, neutrons, and electrons. Nov 25, 2014 - 1 min - Uploaded by mopatin magnet pendulum. Eddy current separation is based on the use of a magnetic rotor with alternating polarity, spinning rapidly inside a non-metallic drum driven by a conveyor belt. Ing magnet field in the iron core induces an eddy current in the magnet The eddy current effect can be reduced significantly by using thin laminations for the. As the electrical transformer is a static device, mechanical loss in transformer normally does not come into picture. This video shows the classic eddy current demonstration, dropping an axially magnetized magnet down a metal tube. Small circular electric fields induced when a magnetic field is created. The eddy current separation method usually sorts this non-ferrous scrap. Induced eddy currents and associated thermal loads is of interest in many high power AC applications.
